IMPROVLED SELF-GLOSIN G HINGE.

TO WHOM IT MAY CONCERN:

Be it known that I, GASPAR VETTER, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Self-Closing Hinge for Doors and Shutters; and I hereby declare the following to be a full1 clear,'an d exact description thereof, reference being had to the accompanying-drawings, making part ot' this specification.

This invention relates to a hinge in which a spring and the force of gravity act iu Lunison to close thedoorv or shutter to which it may be attached. i A

Figure 1 is a perspective View of the several parts of my hinge detached.

Figure 2 shows a door-post and'door furnished with a hinge of my invention.

A is a spindle, having a rectangular top, B, collar, C, shoulder, D, and a reduced part, E, ending in a screw, F, on which is passeda washexgf, and screwed a nut, f. G is a socket-piece, having an interior shoulder, l, above which' the bore H is reduced. The socket-piece G is furnished with a plateor shank,I, for its attachment to the door-post or stile I. Jis a. spiral spring surrounding the vreduced part E of the spindle,

operating against the shoulder t at one end, and the washcrfat the other, to draw the spindle down within the socket. The upper part of the socket G has a rounded recess, g, over the shank I, and from the elevations ou each side of this recess it gradually descends on each side to a concave anele on its4 opposite side g the collar C and shoulder D fits the bore H in the socket. The collar has prominences c and c to suit the concaviticsg and g on the socket. The rectangular top B of the spindle fits and is received into'a suitable socket, K, upon the part L of the hinge, which part is attached to the door M.

It will be observed that my hinge admits of the door swinging in either direction, and gravitates to the point desired. The top B is shown as having four sides, but may have any number over two, which allows ofl the door being placed upon the spindle so as to gravitate to any position, the socket K being made of suitable form to t the top of the spindle.

The operation of the hinge is as follows: When the door is shut, the contiguous surfaces of thc socket G and collar C tit each other around their whole face, the spring J and thel weightof the Adoor operating to keep Y spring speedily close the door. The door, when closed, is held in exact position, more especially by the prominence c and recess y upon the socket and collar respectively.

I claim herein as new, and of my invcntion- Y 1. The combination, with a self-closing door or shutterhinge, operating by gravitation and by a spring, substantially as shown, of the angular or nen-circular top or head B and socket K, permitting the door, when mounted, to gravitate to any desired position, as described. v

2. In combination with the spring J, I claim the inclined edges upon collar C and socket G, having depressions g g and prominenees c c', substantially as shown and described.

In testimony of which invention I hereunto set my hand.

GASPAR VETTER.
